impnotes says:
(EXT:PROBE-DIRECTORY pathname) tests whether pathname exists and is a
directory. It will, unlike PROBE-FILE or TRUENAME, not SIGNAL an ERROR
if the parent directory of pathname does not exist.
This means to me that I should expect a result of T or NIL, at least
if I provide an argument that can be interpreted as a pathname, e.g.,
either "xxx" or #p"xxx".
(ext:probe-directory "/xxx")
*** - PROBE-DIRECTORY: Not a directory: #P"/xxx"
The following restarts are available:

Shouldn't this return nil?
So far I only see how to make it return t and generate the error
above.
